Titans offensive tackle Michael Roos learned on Wednesday that he will have to undergo season-ending surgery on his right knee, according to a report from Jim Wyatt of The Tennessean citing a source close to the situation.
The former Pro Bowler said he's unsure when on Sunday he aggravated the knee. He played all 68 offensive snaps in the 29-28 loss at home to the Browns. After the game, he began to feel discomfort and saw doctors on Monday.
The news comes as somewhat of a surprise, as the 10th-year pro has missed just one game since making his NFL debut in 2005 with the Titans. He was forced to sit after an emergency appendectomy in 2012.
He is being paid $6.625 million this season and becomes a free agent after the season.
Tennessee is 1-4 and third in the AFC South after the loss on Sunday, Roos' 32nd birthday.
